Specification of Letters Patent.

Patented Dec. 30, 1913.

Application led February 27, 1913. Serial N o. 751,115.

To all whom t may concern:

Be it known that I, ETIENNE MARCEL DARQU, a citizen of the FrenchRepublic, and resident at Clichy, France, have invented certain new anduseful Improvements in and Relating to Tin-Box Openers.

This present invention relates to tin-box openers and more particularlyto a device of this kind, whereina cutter or knife is fastened to ashank by means of a hinge, said cutter being movable into its operativeposition for use of the device and collapsible into inoperative positionwhen the device is not in use. i y

The object of the invention is to provide a tin-box opener which may beconveniently placed in xthe operators pocket, without danger of injury.

In the accompanying drawings: Figure 1 shows thel cutter or knife of theopener in side elevation; Fig. 2 is theshank or handle in sideelevation;Fig. 3 is a top plan view showing the device in its collapsed position;Fig. 4 is a perspective view showing the manner of using the device. l y

The essential features ofthe invention consist of thebeak-shaped cutter1, having a slot 2 formed therein and adapted to be engaged by thetongue 3 of the handle 4. Said tongue is curved like a pintle of a hingearound the pin 5 formedby .the slot 2, so

that the cutter 1 may-be collapsed upon the flat handle 4 whenthe deviceis not in use, in order to enable the device to be placed in the pocket.If the device is to be used the knife or cutter 1 will be turned to itso eravtive position and the point thereof w11 be forced into the coverof the box. Now the cutter is raised by means of the handle, the hingeof the latter resting upon the edge of the box whereby the handle workslike a lever. Of course the hinge may be provided with a special guidingdevice, adapted to slide along the edge of the box.

I claim: y

1. A can opener comprising a substantially rectangular `Hat handleprovided with a sleeve` extending longitudinally of one edge, and acutter blade pivotall mounted in said sleeve and `adapted to lie atagainst said handle when in inoperative position.

2. A can opener comprising a handle member consisting of a singlemetallicbplate provided with a substantially rectangular body portionand a portion projecting from one side and rolled to form a sleeve, anda semi-lunate blade member provided with a slot wherethrough theprojecting portion of the handle member passes and pivot-ally connectingthe handle and blade, said sleeve lying wholly to one side of the handlemember whereby the blade may be folded flat against the handle when notin use. y

In testimony whereof I havehereunto set' my hand in presence of twowitnesses.

ETIENNE MARCEL DARQUE.
